National Windmill Day

May 11

One of the iconic symbols of early Western technological innovation in general and the Netherlands in particular, is the windmill, and this day honors these historic machines.

National Windmill Day falls on the second Saturday in May each year, and the festivities are usually held throughout the weekend. Windmills across the Netherlands are decorated and visitors are given demonstrations of their operations. Some windmills also feature special art exhibits or concepts during the weekend.
